select current_timestamp,from_tz(current_timestamp,'Asia/Shanghia') from dual; //因为current_timestamp本身就带有时区,该语句会出现 expected TIMESTAMP got TIMESTAMP WITH TIME ZONE 1. 第一个参数就是不带时区的时间戳,如果带时区就会出错 select from_tz(timestamp '2022-08-25 14:11:30','Asia/S...
然后:在Oracle中没有time数据类型—只有date(足够了,couter-intuitively包括一个时间段)和各种风格的timestamps。如果您希望将输入字符串转换为表示AM/PM格式的time的字符串,则可以执行以下操作: to_char(to_date('T00:00:00', '"T"hh24:mi:ss'), 'hh12:mi:ss am') 这将时间字符串转换为date(日期部分...
常用的日期格式有 yyyymmddhh24miss 和yyyy-mm-dd hh24:mi:ss。 如果时间带AM/PM,那么日期格式可以用 yyyy-mm-dd hh:mi:ssam。 eg: select to_char(sysdate, ’yyyymmddhh24miss ’), to_date(‘2017-06-01 9:25:40’, ‘yyyy-mm-ddhh24:mi:ss’), to_date(‘2017-06-01 9:25:40 PM’, ...
5、current_date、current_timestamp、localtimestamp、sessiontimezone、dbtimezone函数 current_date:9i新增函数,返回当前会话时区所对应的日期时间(date型) current_timestamp:以 timestamp with time zone 数据类型返回当前会话时区所对应的日期时间。 localtimestamp:返回当前会话时区的日期时间 sessiontimezone:返回会...
